Metrop Hydroponics is a specialized line of plant nutrition for argiculture, horticulture and hobby farming. They're known for their high quality liquid nutrition.
After years of cultivation and test experience Metrop Hydroponics looks at the crops in a different way than other nutrition manufacturers.
The most important thought is not to jst look at what a plant needs, but also what it can actually absorb and in which phase of the grow and bloom cyclus.
At Metrop satisfaction is never really reached, the plant nutrition they've developed right now is actually under a loop continiously, they're always looking for ways to make it better and keep innovating.
